2.75+1.48+(3.25-0.48)用简便方法计算
2.75+1.48+(3.25-0.48)用简便方法计算
2.75+1.48+(3.25-0.48)用简便方法计算
(2.75+3.25)+(1.48-0.48)=6+1=7
2.75+1.48+(3.25-0.48)用简便方法计算
-0.5-[-3.25]+2.75-7.5=
(+0.5)+(-3.25)+(-2.75)+(+5.5)
-(+0.5)-(-3.25)+2.75-(+7.
-0.5-(-3.25)+2.75-(+7.5)=( )仔细说明
(一0.5)+(十3.25+(十2.75+-5.5
2.75厚直径0.48米钢管,1米理算重量是多少
(-0.5)-(-3.25)-2.75-(+7.5)怎么算
(-0.15)-(-3.25)+2.75—-(-7.5 )=?
(-0.5)+(+3.25)+(+2.75)+(-6.5)
-1.5减去3.25+(-5.5)的绝对值减去2.75
3又七分之三+3.25-2又二分之一2.7*2.75+6.3*2.75+2又4分之3
负0.5减负3.25加2.75加负7.5等于多少,急啊啊啊啊啊
把0.35,0.13,0.45,0.006,1.03,3.24,2.43,0.4,0.08,1.25,1.4,0.48,0.64化成分数还有2.75,3.2(是最简分数)
17.5:5 98:7 0.25:3.25 15分之8:0.48 1:7分之2 8分之3:0.65 4.2:30% 135%:125%:25% 求比值
请问下列钢材的弹性模量和泊松比分别为多少?钢筋Ф6、Ф8、Ф10、Ф12、Ф14、Ф16;钢管Ф21.25*2.75、Ф26.75*2.75、Ф33.5*3.25
-3-4+19-11+2 、、、、、 (-17)+59+(-37)?还有啦、-0.5-(3.25)+2.75-(+七由二分之1)
1.48千米有多远
